    • A telephony communications approach implements an autodiscover feature that enables an endpoint device to automatically locate and establish communication with a desirable server in a web of interconnected servers. In one specific example implementation, the endpoint device is an internet-type telephone communicating with a remotely-located server in an internet-based private branch exchange. Various packet-communicating endpoint devices are adapted to communicate with the internet-based private branch exchange by adapting each to automatically broadcast its identity and, in response to receiving an assignment for the appropriated iPBX, establish communication with the internet-based private branch exchange from other packet-based servers. Other aspects of the invention are directed to approaches for distinguishing the desired internet-based private branch exchange from the other packet-based servers and implementations for assigning the appropriate iPBX.
    • 电话通信方法实现自动发现功能,其使端点设备能够自动定位并建立与互连服务器的网络中期望的服务器的通信。 在一个具体示例实现中,端点设备是在基于因特网的专用小交换机中与位于远程的服务器通信的互联网型电话。 各种分组通信端点设备适于通过适应每个分组通信端点设备来自动广播其身份,并且响应于接收到专用iPBX的分配来建立与基于因特网的专用小交换机的通信 其他基于包的服务器。 本发明的其它方面涉及用于将期望的基于互联网的私人分支交换与其他基于分组的服务器区分开来的方法以及用于分配适当的iPBX的实施方式。
